2024-10-28 Mechanical Meeting

Announcements

• Please fill out the Regs Q&A with any questions you have for the competition officials: https://utexas.sharepoint.com/:w:/r/sites/ENGR-LonghornRacing/_layouts/15/doc.aspx?sourcedoc={7370fdec-d830-47a7-b7e7-c8c07763392e}&action=edit

• Update on global references for CAD design: https://cloud.wikis.utexas.edu/wiki/spaces/LHRSOLAR/pages/222954747/2024-10-26+Reference+Sketch+Meeting

• Do leads think it is would be beneficial to set up a meeting with Lani to discuss their reference sketch structure?

Highlights

Does anybody have any highlights from the week they would like to share?

Dependency Tree & Timeline

Please link you dependency trees and timelines (as discussed during last leads meeting) below:

Blockers

What is blocking you from starting designing (CAD - even if just preliminary/prototyping)? Do you have any other blockers?

• Geometry but that is accounted for in the timeline

• Figuring out how to use better reference sketches

• Are we changing array size(how much)

• Finalized driver model/roll cage bounding box → ergo jig manufacturing and collected data

• Frame reference sketch → rear hardpoint reference sketch (front is done alr)

• Brake calcs finishing→ Dynamics

• Maximum sizes although we are designing everything to be flexible - once we have max/target sizes we can modify

Workday Review

• Timeline made

• Unsprung worked on our mockup cads, caliper/brake calculations, trailing arm design and collaboration with suspension

• Steering talked to Jacob about RMS error, code, and geometry optimization

Aerodynamics:

• decided on 2 part top shell

• split up everyone into their actual tasks

• maybe a little bit too much high level yapping that they couldnt get involved in which wasnt great

Composites

• continued work on and finished array cooling layups

• Started work on daybreak

• cleaned pickle bc ppl are showing up according to nathan

• sanded a large metal sheet

Frame:

• Mini solids/frame design lecture

• Frame concepts (front and rear) designs continued, close to having preliminary design

• Frame reference sketch created → will have 1st iteration this week

• Composites Research continued → first round of research due this workday

Ergo:

• Pedal box redesign continued (getting closer, pedal ratio redesign finished)

• Brake calcs continued (again, blocked currently)

• Seat outline created for more accurate driver model

• Ergo jig design done → manufacturing this week

• Battery review done, ready to start manufacturing

• Adjustable angle vibe table jig skeleton done

• Intake and exhaust started for battery box

Next Workday Plan - please break tasks down into sub-tasks

• New members join us on newgen geometry design

• Unsprung begins working on CAD for newgen rather than old gen

Aerodynamics:

• Esther goes over how she made daybreak

• Either ANSYS lecture or more time spent working on the parts they have been assigned.

Composites

• Continue surface prep on Daybreak

• Continue research and start working on testing w/the materials that were just ordered (assuming they arrive)

• Continue sanding metal sheet

• Frame ref sketch 1st iteration finished → move to adding weldments

• Ergo jig built → data measurements begin

• Pedal jig printed?

• Manufacturing plans, who’s doing what, hardware, stock, and part inventory

Daybreak Progress?

• From what dynamics understands, y’all are going to do it

• Canopy hinge and shell to shell parts have been assigned to new members and work has actually started

• Frame welding soon?

• Battery review done, ready to start manufacturing

Questions people want to ask:

What do you need from me this week?
